IMPROVEMENT IN PUMPS.

Specication forming part of Letters Patent No. 155,923, dated October 13, 1874; application led l September 15, 1874.

To all whom it may concern:

Be it known that I, EDWARD BUZBY, of Shamong, in the county of Burlington and State of New Jersey, have invented an Improvement in Pumps, of which the following is a specification:

My invention consists in a double-cylinder pump, the cylinders of which have between them a discharge-Valve common to both, and which cylinders consist of two parallel bores in a block of wood, and which pump, with its valves and other parts, as hereinafter more fully described, may be constructed with comparatively simple tools and little mechanical skill, and of material generally at hand in all localities.

The following is a description of my invention, reference being had to the accompanying drawing, in which similar letters indicate corresponding parts in the several lgures.

Figure 1 is a vertical section of my improved pump. Fig. 2 is also a vertical section at right angles with Fig. l. Fig. 3 is a section in the line x Fig. 2, looking in the direction of the arrow. Fig. 4 is a front View of the pump body, showing the central dischargeyalve ory in dotted outline, through the plug k.

A is the pump-body, made ot' a single block ot' wood, in which are bored the cylinders B B', and into which cylinders are fitted suitable pistons C C, connected with a pump handle, b, by suitable rods D D. c c are Valveseats, upon which are tltted the dapper-valves d d. These valve-seats may be made by bushing the cylinders B D after boring, but are preferably' made by boring the cylinders of a less diameter below c c, so as to form a shoulder. e is a dovetailed-formed valve-space, in which plays from side to side the flexible valve, preferably of leather or rubber, a. E is the pump-tube, provided with a spout, F. In the block of which the pump-body is made is bored a vertical cylindrical opening', f, communicating with the valve-space c, and this cylindrical opening forms a continuation ot the bore in the pump-tube E, which latter is most couveniently a bored log tapered to t into j', which is widened at the top to receive it. This Vertical opening f is not in the same plane with axes of the cylinders B B, but is far enough forward or back of said plane to be out of the way of the valve a. Communieatingwith the dovetail-shaped space c is a cylindrical opening, g, from each of the cylinders B B. This cylindrical opening gis made by boring into the pump-block through the vertical axis ofthe cylinder B', and through the dovetail-shaped valve-space cinto the cylinder B, the aperture thus formed between the cylinder B and outside ofthe pump-body being afterward closed by the plug IL. The valve a is Iitted into a cylindrical plug of wood, forniing a valve-stock, t', which is longitudinally slotted to receive it. The valve-stock t' has a dia-meter somewhat greater than the width of the valve-space c at the point where z' passes through it. The valve-space c is most easily made by sawing and chiseling out a dovetailshaped piece from the bottom ot' A, having first bored a hole at t to receive the valvestock. The Valve a being fitted into the valvestock c', the latter is then placed in position, as shown, and the aperture 011 each side ot the pump-body between t' and the top of c, and on each side of the valve a, is then closed by the plugs k k. The pump is supported by and secured to a suitable frame, K, and may be inclosed over the top by a suitable case, L, and is partially submerged, as shown in Figs. l and 2. When one of the pistons C is descending the valve d is thrown across the valve-space c and covers the aperture g on the side of the other cylinder, and liquid is forced up into f while the liquid rises in the other cylinder, the valve c opening to admit it.

I claim- The pumpbody A, composed of a single block of wood with two cylinder-bores side by side, an intervening valve-space, e, a vertical bore, f, meeting the said valve-space, and a transverse bore, g, and having the discharge- Valve carried by a plug inserted through the block and through the valve'space e, the whole constructed snbstantiall y as herein described.

EDVARD BUZBY.
